Entries are first grouped as per SoC present on the board. Groups are
sorted alphabetically. This makes it easy to know SoC to board mapping
and also add new entries in alphabetical order.

The current signal handling tests for SME do not account for the fact that
unlike SVE all SME vector lengths are optional so we can't guarantee that
we will encounter the minimum possible VL, they will hang enumerating VLs
on such systems. Abort enumeration when we find the lowest VL in the newly
added ssve_za_regs test.

During early development a dependedncy was added on having FA64
available so we could use the full FPSIMD register set in the signal
handler. Subsequently the ABI was finialised so the handler is run with
streaming mode disabled meaning this is redundant but the dependency was
never removed, do so now.

Reduce the size of struct symbol on x86_64 from 208 to 200 bytes.

By using calloc() instead of malloc() in a loop, libc does not have to
keep around bookkeeping information for each single structure.
This reduces maximum memory usage while processing vmlinux.o from
3153325 KB to 3035668 KB (-3.7%) on my notebooks "localmodconfig".
Note this introduces memory leaks, because some additional structs get
added to the lists later after reading the symbols and sections from the
original object. Luckily we don't really care about memory leaks in
objtool.

HOSTCC is always wanted when building objtool. Setting CC to HOSTCC
happens after tools/scripts/Makefile.include is included, meaning
flags (like CFLAGS) are set assuming say CC is gcc, but then it can be
later set to HOSTCC which may be clang. tools/scripts/Makefile.include
is needed for host set up and common macros in objtool's
Makefile. Rather than override the CC variable to HOSTCC, just pass CC
as HOSTCC to the sub-makes of Makefile.build, the libsubcmd builds and
also to the linkage step.

Now the type of active_io is atomic. It's used to count how many ios are
in the submitting process and it's added and decreased very time. But it
only needs to check if it's zero when suspending the raid. So we can
switch atomic to percpu to improve the performance.
After switching active_io to percpu type, we use the state of active_io
to judge if the raid device is suspended. And we don't need to wake up
->sb_wait in md_handle_request anymore. It's done in the callback function
which is registered when initing active_io. The argument mddev->suspended
is only used to count how many users are trying to set raid to suspend
state.

mddev->curr_resync = MD_RESYNC_ACTIVE
// e.g., set array as idle
set_bit(MD_RECOVERY_INTR, &&mddev_recovery)
// resync loop
// check INTR before calling sync_request
!test_bit(MD_RECOVERY_INTR, &mddev->recovery

mach-pxa removal
In the work of Arnd's arm multi-platform support, various files in arch/arm
are moved and after the arm mach-pxa removal, only a few files remain to be
not aligned with entries in MAINTAINERS.
These file movements still require adjustments in MAINTAINERS:
Files in arch/arm/mach-ep93xx/include/mach/ are made local:
arch/arm/{mach-ep93xx/include/mach/uncompress.h => boot/compressed/misc-ep93xx.h}
arch/arm/mach-ep93xx/{include/mach => }/ep93xx-regs.h
arch/arm/mach-ep93xx/{include/mach => }/mach/irqs.h
Files in arch/arm/mach-vexpress/ are moved to mach-versatile.
Correct the remaining references accordingly after these refactorings.

Make the following minor changes which were reported by colleagues
while reviewing this code:
- Remove the parentheses from around the LOOP_DEFAULT_HW_Q_DEPTH
definition since these are superfluous.
- Accept other number formats than decimal, e.g. hexadecimal.
- Do not set hw_queue_depth to an out-of-range value, even if that value
won't be used.
- Use the LOOP_DEFAULT_HW_Q_DEPTH macro in the kernel module parameter
description to prevent that the description gets out of sync.
This patch has been tested as follows:
# modprobe -r loop
# modprobe loop hw_queue_depth=-1
modprobe: ERROR: could not insert 'loop': Invalid argument
# modprobe loop hw_queue_depth=0
modprobe: ERROR: could not insert 'loop': Invalid argument
# modprobe loop hw_queue_depth=1; cat /sys/module/loop/parameters/hw_queue_depth
1
# modprobe -r loop; modprobe loop; cat /sys/module/loop/parameters/hw_queue_depth hw_queue_depth=0x10
16
# modprobe -r loop; modprobe loop; cat /sys/module/loop/parameters/hw_queue_depth hw_queue_depth=128
128
# modprobe -r loop; modprobe loop hw_queue_depth=129; cat /sys/module/loop/parameters/hw_queue_depth
129
# modprobe -r loop; modprobe loop hw_queue_depth=$((1<<32))
modprobe: ERROR: could not insert 'loop': Numerical result out of range

depth").

NVMe In-Band authentication uses two kinds of works: chap->auth_work and
ctrl->dhchap_auth_work. The latter work flushes or cancels the former
work. However, the both works are queued to the same workqueue nvme-wq.
It results in the lockdep WARNING as follows:
WARNING: possible recursive locking detected
6.2.0-rc4+ #1 Not tainted
--------------------------------------------
kworker/u16:7/69 is trying to acquire lock:
ffff902d52e65548 ((wq_completion)nvme-wq){+.+.}-{0:0}, at: start_flush_work+0x2c5/0x380
but task is already holding lock:
ffff902d52e65548 ((wq_completion)nvme-wq){+.+.}-{0:0}, at: process_one_work+0x210/0x410
To avoid the WARNING, introduce a new workqueue nvme-auth-wq dedicated
to chap->auth_work.

The nvme driver will freeze the IO queues in response to an admin
command with CSE bits set. These bits notify the host that the command
that's about to be executed needs to be done exclusively, hence the
freeze.
The Security Receive command is often reported by multiple vendors with
CSE bits set. The reason for this is that the result depends on the
previous Security Send. This has nothing to do with IO queues, though,
so the driver is taking an overly cautious response to seeing this
passthrough command, while unable to fufill the intended admin queue
action.
Rather than freeze IO during this harmless command, mask off the
effects. This freezing is observed to cause IO latency spikes when host
software periodically validates the security state of the drives.

Instead of appending command effects flags per IO, set the known effects
flags the driver needs to react to just once during initial setup.
